It will I have done it for years.There is a long thread elsewhere in this forum about using a cider vinegar mix (50/50 with water) to control dandruff. It was said this worked for some time, but not indefinitely. The OP then started using something else. I just started the cider vinegar process (I left mine in instead of rinsing and the smell subsided within 15 minutes or so) to help with dandruff. I hope it works. I can tell my hair is really soft today. Time will tell.
